Back-to-school time reminds me of my first year of school many years ago in Sauk Center, Minnesota. There, one of my favorite kindergarten activities was making butter in the classroom. I’d helped my family make butter at home in a stoneware churn, but at school we did it differently. All of the students sat in a circle where we took turns passing a jar of cream. We shook, shook, shook that jar with all our might and then passed it along to the next student. Eventually, the cream began to thicken. When it had turned to butter, our teacher added a pinch of salt and then we spread the fresh butter on crackers and enjoyed the tasty treat.
